s (ci. ess-19) This invention relates to a window regulator adapted to control both a swinging window and a sliding window. Automobiles are today almost universally provided with the so-called Fisher no-draft Ventilating system. This consists of a forward window panel which swings on an interl mediate up and down axis and a rear vertically sliding panel. These are ordinarily controlled by separate window regulators operated by separate cranks. It is the object oi' the present invention to aord a power-operated window regulator mechanism which can operate both the panels. This mechanism us one source of power and is controlled by separate switches or buttons. The same driving and power connections operate both mechanisms and the selective operation of each is controlled by a suitable clutch.

2 represents lthe sliding panel. This sliding panel is guided vertically in window runs not shown and is raised and lowered by a cable type oi regulatorprovided with a lift pin 3 which engages in the notch 6 in the window bracket 4. The pin is locked in this notch by means of the hook 9 which has a notch 1. The cable 3 passes over the upper sheave 9 and over the lower sheave I0 which is supported on a slide Il which is spring-pressed 4by spring I2 to put the cable under tension. The cable passes also over the idling sheaves I3 and I4 and then passes horizontally to the left where it passes overk the driving pulley I 3.

Refer toFg. 2. This driving pulley "has a portedinballbearing. Thisshaftcarriesa wormwheelil. Ontheendoftheshaftisa spiral counterbal'ancing spring i9, one end oi Y which as at 26 is secured to the shaft and the other end secured to the gear housing 2|. The worm wheel is driven by worm 22. Worm 22 is supported loosely on shaft 23. 'I'his is the motor On the upper yend of the shaft a worm 2&1 lits loosely and meshes with the worm gear 29 .which is keyed on worm shaft 29 (Fig. 6). Also keyed on this shaft is a second worm 21 which meshes with the worm gear 28. 'I'his worm gear is a part of a casting 29 (Fig. 9) which forms a journal for the gear and is rotatably supported in housing 30. The top of this journal is slotted as at 3l to receive the ilattened spindle 32 which is connected to the bottom of the swinging panel I.

The two driving worms 22 and 24 drive the cable regulator and the C. V. regulator, respectively, and are coupled to the drive shaft by means of a jaw clutch 33. Here it might be explained that the swinging panel regulator is called the C. V. regulator", because this is how it is designated in the Fisher no-draft Ventilating system-the C. V. is an abbreviation for Controlled ventilation. Clutch 39 has a slidable clutch sleeve 34 with teeth at each end arranged to engage in notches 35 in the worm 24 or notches' 36 in the end of worm 22. This sleeve is splined on the drive shaft 23 by means of spline 31. 'I'hls sleeve is ordinarily in a neutral position as shown in Fig. 7, but it can be shifted either to engageworm 22 or worm 24 by means of the in a central position by springs 44 and 45.

Shaft 23 is driven by motor M. Motor M is controlled by two-circuits, one connecting with 'I switch buttons adjacent the C. V. panel, one button to control the circuit that will rotate lthe motor armature in one direction, the other button to control the circuit to rotate the motor armature in the opposite direction. Each of these circuits passes through the solenoid 39 which urges the clutch to drive the worm 24. In each of these C. V. regulator circuits are limit switches 46 and 41 which are operated by cam 48 on the C. V. panel spindle 32. 'I'here are alsotwo circuits in connection with the cable regulator controlled by switch buttons located adjacent the sliding panel,

one circuit serves to rotate the motor in one direction and the other circuit the motor in the opposite direction. Limit switches 4l and I5 can be located in these circuits and thereby break the current when the sliding panel reaches the limit of its travel either up or down.

ReferringtoFig. lthewiringdiagramwillbe found. Switch 52 is pivoted at 5| and adapted to control the two sliding panel circuits referred to above. Rotating the switch 52 in a counterclockwise direction will close the circuit from battery B through wire 58, wire 54, limit switch 48, motor M, ground 80 and ground 5| on the battery. This causes the motorl to rotate in a direction to lower the slide paneL At' the same time, current will flow from wire 53 through switch 52, wire 62, solenoid 48, ground 63 and back to ground 8| on the battery to energize solenoid 40 which couples the motor with the worm 2| to drive the cable regulator. When the window reaches the lowermost limit of its travel, it can break the circuit at thel limit switch 49. Rotating switch 52 in a clockwise direction will set up a circuit through wire 58, wire 64, limit switch 58,.wire 65, motor M, ground 60 and ground 6I. At the same time, current will ilow from wire 53 through wire 62, solenoid 40, ground 63 and ground 6| to energize the solenoid 48 to couple the motor with the worm 2|. In this circuit with current passing through line 65 instead of line 54 into the motor, the motor isl rotated in a direction to raise the window. When the window reaches the upper limit of its movement it will break the circuit at limit switch U.

To control the C. V. ventilator a switch 66 is pivoted at 61. Rotating switch 66 in a clockwise direction will establish a circuit from battery B through wire 68, wire 68, limit switch 46, motor M, ground 60 and ground 6|. At the same time, current will flow from wire 68 through wire 10, solenoid 39, ground 1i and ground 6I. By energizing this circuit the motor will be rotated to turn the C. V. ventilator outwardly and the solenoid 89 is energized to urge the clutch to drive the worm 24. When cam 48 strikes limit switch 46, the circuit will be broken and the motor stopped. When the switch 66 is rotated in a counterclockwise direction a circuit is established from battery B through line 68, line 12, limit switch 41, motor M, ground 60 and ground 6|. At the same time, current flows from line 68 through line 18, solenoid 39, ground 1| and ground 6I. This will turn the rear end of the ventilator panel in and close the window. Cam 48 will strike limit switch 41 and break the circuit to stop the motor.

The control switches 52 and 66 can be located at any convenient point on the body or on the instrument board. The solenoid, if desired, can b used in connection with a single manually operated handle to operate either the C. V. member or the sliding member.
